Is connected to the main control unit 20 via a bus line 21.

The cable covering materials 101, 102, 103,
Since the first to fourth cords 41 to 44 using the cord 104, the cord inspection device 50, and the like have the above-described configurations,
When performing the damage inspection of the first to fourth codes 41 to 44 shown in FIG. 5, first, the damage inspection start signal S1 shown in FIG. 6 is input from the keyboard 17 of the code inspection device main body 10 shown in FIG.
Is input to the main control unit 20. Then, the main controller 20
Is the radio wave generation and output unit 1 based on the inspection start signal S1.
A damage inspection start command S2 is output to the radio wave receiver 3 and the radio wave receiver 15. Then, the radio wave generation / output unit 13 generates a radio wave Wo1 having a predetermined first frequency based on the damage inspection start command S2, and outputs the radio wave Wo1 from the transmission / reception antenna 12. Further, when the transmission / reception antenna 12 receives the radio wave Wi2 having the predetermined second frequency based on the damage inspection start command S2, the radio wave receiving unit 15 damages the positive signal S3 while receiving the radio wave Wi2. The output continues to the detection unit 16. The damage detector 16 receives the positive signal S3 from the radio wave receiver 15
It is determined that the first to fourth codes 41 to 44 are not damaged, and when the positive signal S3 is not input, it is determined that the first to fourth codes 41 to 44 are damaged and the alarm control unit 11 is notified. The alarm signal S4 is output. The alarm signal S4 continues to be output while the correct signal S3 is not input to the damage detector 16. The alarm controller 11 controls the alarm 18 to emit an alarm sound only while the alarm signal S4 is being input. Therefore, a worker (not shown) holds the cord inspection device main body 10 shown in FIG. 5 by the shoulder strap 22, holds the transmission / reception antenna 12 in hand, and turns the transmission / reception antenna 12 toward the floor plate 30. Then, the radio wave Wo1 emitted from the transmitting / receiving antenna 12 passes through the floor plate 30 and reaches below the floor. The worker moves the transmission / reception antenna 12 on the floor plate 30 to search for any one of the positions of the first to fourth cords 41 to 44 provided under the floor plate 30. If there is nothing under the floor plate 30 below the transmission / reception antenna 12, the transmission / reception antenna 12 does not receive the radio wave Wi2 of the predetermined second frequency described above, and thus the alarm sound continues to sound. Therefore, when the warning sound stops, the transmitting / receiving antenna 12
Any one of the first to fourth cords 41 to 44 is located under the floor below. When the radio wave Wo1 hits any one of the first to fourth cords 41 to 44, the insulation tubes 1A, 1B, 1C and 1D of the first to fourth cords 41 to 44 have a predetermined first frequency. Resonant member 5A that resonates with radio wave Wo1 and emits radio wave Wi2 having a predetermined second frequency,
Since the 5B, 5C, and 5D are built in, the resonance member 5
Radio waves Wi2 are emitted toward the transmitting / receiving antenna 12 by A, 5B, 5C, and 5D. Then, the transmission / reception antenna 12 receives the radio wave Wi2, so that the alarm sound stops as described above. Therefore, the worker
By moving the transmitting / receiving antenna 12 in the direction in which the alarm sound does not sound, the wiring locations of the first to fourth cords 41 to 44 can be detected.

Further, any one of the first to fourth cords 41 to 44 is damaged, and the resonance members 5A, 5B, 5C, 5D.
Is broken or damaged, at the damaged portion 8, the resonance members 5A, 5B, 5C, 5D resonate even if they receive the radio wave Wo1 of the first frequency due to the break or damage. Radio wave W of a predetermined second frequency
Since it becomes impossible to emit i2, an alarm sound will sound. The principle is the same as above. Therefore, the damaged portion 8 of the first to fourth cords 41 to 44 can be easily detected without removing the floor plate 30.

After detecting the damaged portion 8, the worker next detects which of the first to fourth cords 41 to 44 the cord is. Therefore, first, the tag information read signal S5 shown in FIG. 6 is input to the main controller 20 from the keyboard 17 of the code inspector main body 10. Then, the main control unit 20 outputs the tag information read command S6 to the radio wave generation output unit 13 and the radio wave reception unit 15 based on the tag information read signal S5. Then, the radio wave generation / output unit 13 generates a radio wave Wo3 having a predetermined third frequency, a radio wave Wo4 having a predetermined fourth frequency, and a radio wave Wo5 having a predetermined fifth frequency based on the tag information reading command S6, and the transmitting / receiving antenna Output from 12. Further, the radio wave receiving unit 15 sends the first signal S7 when the radio wave Wi6 of the predetermined sixth frequency is received by the transmission / reception antenna 12 based on the tag information reading command S6.
When the radio wave Wi7 having the predetermined seventh frequency is output to the tag information reading unit 14, the second signal S8 is output to the tag information reading unit 14 and the radio wave Wi8 having the predetermined eighth frequency is received. Then, the third signal S9 is output to the tag information reading unit 14. Then, the tag information reading unit 14 checks the combination of the input first signal S7, second signal S8, or third signal S9 against the catalog that has been input in advance, and the first to fourth codes 41, 42. , 43, or 44 is detected. Then, the tag information reading unit 14 detects the name N1 or N2 of the detected code.
Alternatively, N3 or N4 can be output to the display 19. Therefore, as shown in FIG. 5, the worker moves the transmitting / receiving antenna 12 so as to follow the second cord 42 where the damaged portion 8 is found. Then, the second code 42 includes a plurality of information elements 6B, the resonance member 5
Since they are built in along A, 5B, 5C, and 5D at equal intervals, a radio wave Wo3 of a predetermined third frequency, a radio wave Wo4 of a predetermined fourth frequency, and a radio wave of a predetermined fifth frequency emitted from the transmitting / receiving antenna 12 are generated. Wo5 is a transmitting / receiving antenna 1
If 2 follows the second code 42 and moves, it will hit the information element 6B without fail. Also, the information element 6B
When receiving the radio wave Wo3 having a predetermined third frequency, the radio wave Wo4 having a predetermined fourth frequency, and the radio wave Wo5 having a predetermined fifth frequency output from the transmitting / receiving antenna 12, only the radio wave Wo4 having the predetermined fourth frequency is received. Since it resonates and emits a radio wave Wi7 having a predetermined seventh frequency, the transmitting / receiving antenna 12 is
The radio wave Wi7 having the seventh frequency is received. Then, the radio wave Wi7 is input to the radio wave receiving unit 15 shown in FIG. Then, the radio wave receiving unit 15 outputs only the second signal S8 to the tag information reading unit 14 based on the radio wave Wi7. Then, the tag information reading unit 14 detects that the code 42 is the second code 42 based on the fact that only the second signal S8 has been input, by comparing it with the catalog that has been input in advance. Then, the tag information reading unit 14 outputs the detected code name N2 to the display 19. Then, the display 19 displays the code name N2.
Is displayed. As a result, the worker does not remove the floor board 30 without removing the name N2 of the code 43 having the damaged portion 8
You can easily know.

Therefore, the worker can know the wiring location of the damaged cord 42 and the name N2 of the cord 42 without removing the floor plate 30. Therefore, when exchanging the cord 42, the replacement cord is required. It can be prepared in advance, and the work can be performed only by removing the minimum necessary floor boards 30. Therefore, the work can be performed easily and quickly.

Further, the code inspecting device 50 is used in a place where there are a plurality of cables such as the first to fourth cords 41 to 44, such as a material storage, even when the name of the cable is detected. Can be detected easily and quickly.

Further, the noise shield material 2A shown in FIG.
2B, 2C and 2D are cables 3A, 3B, 3C and 3D
